I'm looking for the Gland nut (hex) for one of the cylinders on our naa. I went to put new V-packing in it, when I took it apart the first 1/2 inch of threads are messed up, looks as if water got in and rusted them away and I'm not sure there are enough good threads to compress the V-packing. Does anyone have an old H800-46 Wagner cylinder they can part out for that part? Thanks and God Bless, Beth and Allen.
